Does it 8 Times over, it's serious Govt Spec stuff. Won't do individual files though.

Yeah, before they removed the REAL dos from Windows installations this could be done by rebooting into DOS mode and deleting through DOS. One of the reasons deleting would take 10 minutes in DOS and 2 seconds in Windows.
Most "deleting" nowdays if i'm not mistaken is just removing the index and marking the diskspace as writable without removing the info. Hence the ability to recover deleted files durring criminal investigations.
